:To all ii -hem it may concern-f Be itknowu that-we, THOMSON MoGowAN, OfDIBITBdit-hj Venzmgo county, State of Pennsy-lvania-l; and SAMUEL VAN SYGKEL, ofTitusville, (,r'awford. county, State of Pennsylvania, Junie invented a-n Improved Feed-Pipe for song int-he Distillatiouof Hydroearbqns,

ot' whielnthe following is a specification I Our intention relates to the proeesses of distillation III which the separation of the componont parts of the crude material iseil'oeted by mea-ns' of heat.

' The composition of hydrocarbons as'ordinwrily obtained; being a mec lanicnlcombination of one or more series (pt separate. and distinct h ydroearhons having /eoch' its special proportion of carbon and hydrogen, and the difference between each of the several members ot'.these series being very slight, it hasboen' found in the ordinary practice of distillation,

that, in drawing off by heat applied in the usual manner toe body of crude oil or. other. product; it is desirnllleto separate perfectly;

and distinctly each" member of the seriefi of hydrocarbonsconsecutively in theorder of itsf gravity; hutin vaporizing the lighter hydro can-lions hy the noun] method, it ie found that pints of the; henvi'er nydroenrhons are meo chnnicirlly combiner, and taken/with them,

, givinga colored andimpontbetdistillate.

'lhcdrawing shows the section of an ordinary still into which our improved feed-pipe is introdneeih F is the" feed-pipe of the crude product, whiehis regnlatedjby the flout l3 and the hinged lever C. Whenthe oil in the still is' low, as indicated lly the position of the iioot and lever B 0", the stop-cock is opened by thelever, and the oilallowed to flow-in. When the oil'has filled the sitill to the line G, the.

action of the float and lover closes the stopeoclt. After leaving the stop-cook the oil passes through the pipes A A A, in two in more eoi-lsyas may be desired, and are shown.

0n the upper sides ofeach of the horizontal pipes @series of openings, it It, ere mede to allow/of the escape of those lrwlroombons which the heat of the pipe at that place will vaporize. As the oil passes slowly through the pipe, it receives gradually more and more he'zmond when it finally falls from the pipe into the still, ,it is already freed from the lighter lq'dl oc orbons,and contains only the heavier members of the series, which it will quire the full heat of the still to rename.

, We elniifias our invention- A pert'orated coil-pipe arranged within, a: still ZLXHLGOHIlGCtHl with a' feed-pipe, Millstontlnlly as described, whereby the lrydroezirhons introduced are vaporized and nllowed to eh"- enpethi'oug'h the perforations in the older of their respective griwities, us the hydrooiirhon travofrses the pipe. l o
